Thread locking and sealing for screws and bolts to prevent loosening under vibration, corrosion and leakage.
Low strength (purple): hand removable, for small screws; e.g. 222
Medium strength (blue): removable with tools, for general mechanical bolts; e.g. 243
High strength (red): hard to remove, for heavy-duty locking; e.g. 271/272
Advantages:
One-component, no mixing required, cures at room temperature. No UV lamps or heating equipment needed.Vibration-resistant, oil-resistant, solvent-resistant, operating temperature range: -54~150℃. Some models feature high temperature resistance.Provides both locking and sealing functions to prevent thread rust and corrosion.Excess adhesive does not cure and is easy to clean. Solvent-free with low VOC.
Anaerobic Curing Mechanism Single‑component acrylic formula, remains liquid in contact with air. Cures at room temperature when confined in tight metal gaps without oxygen, no heating or UV light required.
Anti‑vibration Locking & Sealing Effectively prevents bolts and screws loosening caused by shock and vibration, provides sealing against oil, gas and liquid leakage, protects threads from rust and corrosion.
Wide Metal Compatibility Works well on active metals like steel and copper. For passive substrates such as stainless‑steel, aluminum and plated surfaces, use activator to speed up curing.
Multiple‑purpose Industrial Application Available for thread locking, cylindrical parts retaining, flange surface sealing, micro‑crack impregnation for mechanical equipment assembly.
Important Notes Proper gap ≤0.15mm for full curing. Excess glue outside joint stays uncured and easy to wipe off. Reach full strength within 24 hours under normal room temperature. Not fit for wood, rubber and most plastics.
222:Low-strength purple anaerobic threadlocker, for small-size fine threads up to M6. Easy disassembly with ordinary hand tools, prevent loosening and leakage for tiny metal screws.
242:Medium-strength blue anaerobic adhesive, general-purpose removable threadlocker for most common metal bolts M6-M20. Can be disassembled by standard hand tools.
243:Medium-strength blue threadlocker with enhanced oil tolerance. Removable, designed for metal parts with residual cutting oil, M6-M20.
262:High-strength red anaerobic threadlocker. For M6-M20 heavy-load bolts. Normally non-removable; disassembly requires heating above 250℃ plus hand tools.
271:Ultra-high strength red anaerobic adhesive for large heavy-load threads up to M36. Permanent locking, disassembly needs high-temperature heating.
272:High-temperature resistant high-strength red threadlocker. For bolts working under continuous high-temperature environment, M6-M20.
277:High-viscosity high-strength red anaerobic threadlocker for large threads up to M36. Excellent anti-dripping for vertical large bolts, permanent locking, remove by heating.
290:Low-viscosity green wicking-type anaerobic threadlocker. Capillary penetration into pre-assembled tiny thread gaps. Medium removable strength, suitable for already-assembled small fasteners, porous threads and micro-cracks.
